so加形容词的倒装句是半倒，还是全倒
as, though 引导的倒装句as \\\/ though 引导的让句必须将表语或状语提前（名词，词, 副词, 分词, 动词提前）。
Old as they were, they stuck to working. 虽然他们年纪大了，还在坚持工作。
Pretty as she is, she is not clever. 虽然她漂亮，但不聪明。
Tired as he was, he worked late into the night.虽然他累了，但还是工作到深夜。
Hard as he tried, he couldn't lift the stone. 虽然他很努力地尝试了，但是还是没有搬动那石头。
Young as he is, he knows a lot. 虽然他年轻，却知道很多东西。
但需注意：1） 句首名词不能带任何冠词。
例如：Child as he is, he speaks English very well2） 句首是实义动词, 其他助动词放在主语后。
如果实义动词有宾语和状语，随实义动词一起放在主语之前。
例如：Try hard as he will, he never seems able to do the work satisfactorily. 他工作很努力，但总不能让人满意。
注意：让步状语从句中，有though，although时，后面的主句不能有but，但是 though 和yet可连用。
由as引导的部分倒装句 怎么用
a) 当as作为比较意义时，即用于as + adj.\\\/ adv. + as结构中时，如果把第一个as省略掉，就形成部分倒装句。
例：Cautious as the rest of her family (was) , she didn't seem willing to give an immediate reply to my question.（正如她家里人一样谨慎小心，她似乎不愿意立即回答我的问题。
） She ran down the stairs, quick as a rabbit (ran).（她跑下楼去，跑得象兔子那么快
b) 当as引导让步状语时，和although, though一样，当用作“尽管”之义时，可以用于部分倒装句。
例：_______, there was no hope of her being able to sleep. A) As she was exhausted B) If she was exhausted C) Exhausted though she was D) Now that she was exhausted 答案是C) Exhausted though she was。
从属连词as, though可以用于让步状语从句中。
这种从句必须以形容词（或形容词化的分词）、名词或动词原形开头，主语必须位于从句之后。
D) Now that she was exhausted里的引导词Now that表示“既然”；B) If she was exhausted表示条件“如果”； A) As she was exhausted表示“由于”（因为使用的是正语序），都与后面句子的意思不通顺。
c) 表示原因时，为了强调起见，也可以倒装。
例：Tired as he was, we decided not to disturb him. （因为他太累了，我们决定不打扰他。
）d) 等于so时，意义是“也，也是” 例：She worked hard, so\\\/ as did her husband. （她工作很努力，她的丈夫工作也很努力。
）3. 其它情况的倒装句 1) so, neither, nor除了构成上述倒装句以外，还可以取代上文出现的名词、形容词甚至整句话， 构成 完 全倒装句或部分倒装句。
但这两种倒装的意义不同。
a) 当so表示“也，相同，那样”时，通常表示对前一句肯定句的赞同、一致内容， 要求使用 完全倒装句： 例：I asked him to complete the experiment before five, so he did (=and he did that).（我让他在5点以前完成实验，他做到了。
） b) so \\\/such ……that句型可以构成部分倒装句，表示强调so \\\/such和that之间的部分： 例：So unreasonable was his price that everybody startled.（他的要价如此之高，令每个人都瞠目结舌。
） To such length did she go in rehearsal that the two actors walked out.（她的彩排进行得那么长，以致于两个演员都走出去了。
） c) neither和nor共有4种倒装形式，其含义分别为： 完全倒装时：表示也不，和上文a）用法正好相反， 表示对前一句否定句的赞同或一致内容。
例：You don't know what to do now, neither\\\/ nor do I .（你不知道现在该做什么，我也不知道。
） 和其它否定副词连用，表示也（不），也要求用完全倒装句： 例：The besieged enemy could not advance, nor \\\/ neither could they retreat.（被包围的敌人既不能进，也不能退。
） 注意：若把这句话改成：The besieged enemy could neither advance nor retreat.（被包围的敌人既不能进，也不能退。
）就不必倒装。
例：She never laughed, ______ lose her temper. A) or she ever did B) nor did she ever C) or did she ever D) nor she ever did 本题的句子是一个并列句，全句意思是：“她从来不大声笑，也没有发过脾气”。
当前面的分句含否定意义而且后面的分句也含否定的意思时，后面的反句通常用含否定意义的nor（或neither）连接。
此外，nor（或neither）连接的分句应当用倒装句，及其谓语中的情态动词、连系动词或助动词应放主语之前。
所以B) nor did she ever是答案。
本句相当于：…, and she never lost her temper, either。
1) 用在肯定句里，构成一般否定倒装： 例：All that is true, nor must we forget it.（那全都是真的，我们可不能忘记。
） 2) 部分倒装，有承上启下作用，表示同意和赞同： 例：A: I couldn't do anything for her.（我帮不了她。
） B: Nor you could, but you might have got somebody to help her.（你是不能帮她，但你本可以找人帮她的。
） 2) 在进行比较的句子里，如果主语不是代词时，可以倒装： 例：America consumes more energy than did our country.（美国消耗的能源比我们国家多。
） Her face is rather pale and even paler are her hands.（她的脸色苍白，她的手更白。
）
as引导的倒装句
As引导让步状语从句的用一、名词 + as \\\/ though + 主语 + 动词 King as he was，he was unhappy. 他虽是国王，但他并不幸福。
Child as he is，he knows to help other. 他虽是个，却知道帮助别人。
【说明】其中的动词通常为连系动词，也就是说位于句首的名词是其后连系动词的表语。
另外，要特别注意位于句首的名词前习惯上不用冠词，即使其前有形容词修饰也不用冠词。
比较：Boy as ［though］ he is， he likes to play with girls.=Though he is a boy，he likes to play with girls. 他虽是男孩，却喜欢与女孩子玩。
Strong man as ［though］ he is，General Botha has been severely put to the test during the past few weeks.= Though he is a strong man， General Botha has been severely put to the test during the past few weeks. 波赛将军虽然坚强，但在过去的数周里也受到了严峻的考验。
二、形容词 + as \\\/ though + 主语 + 动词 Successful as he is，he is not proud. 他虽然成功，但不骄傲。
Improbable as it seems，it’s true. 虽然看起来不太可能，但却是真的。
Stupid as it sounds，I was so in love with her that I believed her. 尽管听起来很愚蠢，我是如此爱她竟然相信了她的话。
Patient as he was，he didn’t like waiting that long. 他虽说有耐心，也不愿等这么长。
Beautiful though the necklace was，we thought it was over-priced. 那条项链虽然很漂亮，我们认为价钱太高。

He was unable to make much progress，hard as he tried. 尽管他做了努力，却未能取得很大进步。
【说明】有的词典将 much as 作为习语看待，认为它是一个用以引导让步状语从句的复合连词。
再如：Much as I admire him as a writer，I do not like him as a man. 他作为一名作家我很佩服他，但我却不喜欢他这个人。
Much as I like you，I couldn’t live with you. 我尽管很喜欢你，却不能和你在一起生活。
四、动词原形 + as \\\/ though + 主语 + 动词Object as you may，I’ll go.纵使你反对，我也要去。

五、分词 + as \\\/ though + 主语 + 动词Raining hard as it is， I’m going out for a walk. 虽然正在下着大雨，我还是要出去散步。

Munching the apple as he was，he had got an eye for all John’s movements. 他尽管在一个劲地嚼着苹果，但仍警惕着约翰的一举一动。
AS倒装句首名词可否用复数
当然可以，as倒装就是把as后面的成分提到前面来，起强调作用。
名词、形容词、副词、动词原型都能放前头，比如:young as they are（形容词提前）much as he like it(副词提前）try as they might（动词提前）要注意的是名词单数提前的时候，要去掉冠词，比如：child as he is
